金强河地区豆科牧草引种试验报告

1983—1985年,在海拔高度约3千米的甘肃省天祝基金强河地区进行了豆科牧草引种试验。通过对48个豆科牧草供试材料的生育期、越冬率、产草量等性状的观测研究,初步筛选出抗寒性强、越冬性较好的呼盟黄花苜蓿、昭盟黄花苗蓿 x 杂种苜蓿、杂种苜蓿、草原Ⅰ号苜蓿、润布勒苜蓿五个材料,供生产上试种。通过试验,说明越冬前灌水和覆盖处理对提高豆科牧草越冬率有良好作用。此外,还观察到了一些具有放牧型品种特征的,以及长穗的,可作为有价值的育种材料加以利用。

The Introduction Experiments of Forage Legumes at Jinqiang He Area in Tianzhu County of Gansu Province
